Information:
voltage is 24 3 VDC.Results:
OK - The voltage is 24 3 VDC.Repair: Check wire G701 for continuity between ECM connector P2-6 and terminal BH of the customer connector. If necessary, repair the wire. If wire G701 is OK, repair the wiring or devices on the customer's side of the customer connector.STOP
Not OK - The voltage is not 24 3 VDC.Repair: Check the electrical power to the ECM. Refer to Troubleshooting, "Electrical Power Supply".Verify that the engine prelube is operating correctly. Refer to Troubleshooting, "Prelubrication System".If the above systems are operating correctly, the problem may be in the ECM. Refer to Troubleshooting, "Replacing the ECM".STOPTest Step 5. Check the Start Signal from the MPD Panel
If an electric starting system is installed on the engine, perform the following step.
Remove wire E701 from terminal 9 of connector "G-C6" at the MPD panel. Connect one end of a voltmeter to the −Battery terminal. Connect the other end of the voltmeter to terminal G-C6-9.
If an air starting motor system is installed on the engine, perform the following step.
Remove wire G701 from terminal 13 of connector "G-C6" at the MPD panel. Connect one end of a voltmeter to the −Battery terminal. Connect the other end of the voltmeter to terminal G-C6-13.
Turn the ECS to the START position.
Monitor the voltage on the voltmeter.
Turn the ECS to the OFF/RESET position.
Reconnect all wires. Expected Result:The voltage is 24 3 VDC.Results:
OK - Electric starting system - The voltage is 24 3 VDC on terminal 9 of connector "G-C6". Proceed to Test Step 6.
OK - Air starting motor system - The voltage is 24 3 VDC on terminal 13 of connector "G-C6". Proceed to Test Step 12.
Not OK - The voltage is not 24 3 VDC.Repair: Verify that 24 3 VDC is present on terminal 10 of connector "G-C6" at the MPD panel. If voltage is not present on terminal 10 of connector "G-C6" at the MPD panel, repair the wire F701 between terminal 10 and terminal BJ of the customer connector.If voltage is present on terminal 10 of connector "G-C6" at the MPD panel, repair the wiring between terminal 10 of connector "G-C6" at the MPD panel and either terminal 9 or terminal 13 of connector "G-C6" at the MPD panel.STOPTest Step 6. Check the Start Signal from the Power Distribution Panel
Remove wire E701 from the engine side of terminal f of connector "P-C1" at
OK - The voltage is 24 3 VDC.Repair: Check wire G701 for continuity between ECM connector P2-6 and terminal BH of the customer connector. If necessary, repair the wire. If wire G701 is OK, repair the wiring or devices on the customer's side of the customer connector.STOP
